Erik Holstad commented on HBASE-1249:
-------------------------------------
The pdfs looks really good and they make sense to me, just hope that they can
help others to understand what we are going for here.
Just a couple of things that are a little bit unclear to me in the examples:
DeleteFamily in MemCache, should probably have a different ts, to belong there,
same thing with stuff in the storefiles.
For the GetColumns(RowA, Fam, [ColA, ColB], ts(20, 0)), I would think that that
query would mean give me 1 version of
ColA and ColB from the timeperiod 20 - 0.
And for GetFamily(RowA, Fam, num=1), Couldn't you early out as soon as you
encounter the DeleteFamily in MemCache?
> Rearchitecting of server, client, API, key format, etc for 0.20
